The webSocket message class cannot generate a document

[shalousun]

@PGJiang Can you provide some additional code examples?

I have the same issue ,my code as follow: @ServerEndpoint("/documents/did/{did}/bid/{bid}") @RestController public class DocumentWebSocketController {

@OnMessage
public void receive(String message, Session session, @PathParam("did") int documentId,
                    @PathParam("bid") String branchBid) {

In WebSocket programming, it's common to handle URL parameters within the @OnOpen method, where the WebSocket session is established, rather than in the @OnMessage method. Here’s an example of how you might do this:

@ServerEndpoint("/documents/did/{did}/bid/{bid}")
@RestController
public class DocumentWebSocketController {

    private int documentId;
    private String branchBid;

    /**
     * Handles the opening of a WebSocket connection.
     *
     * @param session   the WebSocket session
     * @param documentId the ID of the document
     * @param branchBid the ID of the branch
     */
    @OnOpen
    public void onOpen(Session session, @PathParam("did") int documentId,
                       @PathParam("bid") String branchBid) {
        this.documentId = documentId;
        this.branchBid = branchBid;
    }

    @OnMessage
    public void receive(String message, Session session) {
        // You can now use documentId and branchBid here
        // Example usage:
        System.out.println("Received message: " + message + " for Document ID: " + documentId + " and Branch ID: " + branchBid);
    }

    @OnClose
    public void onClose(Session session) {
        // Handle close event
    }
}

By defining the parameters in the @OnOpen method, you can store them as instance variables and use them across the WebSocket session, including in the @OnMessage method. This approach helps keep the @OnMessage method focused on processing messages rather than extracting path parameters.

You can refer to this example: @OnOpen

Thank you for your reply! My code is meet the requirement which you discribe, but it can't gen the api document. My code is follow: maven plugin :

com.ly.smart-doc

            <artifactId>smart-doc-maven-plugin</artifactId>
            <version>3.0.7</version>

@Slf4j
@ServerEndpoint("/documents/did/{did}/bid/{bid}/mid/{mid}")
@RestController
public class DocumentWebSocketController {
    private static final int HEARTBEAT_TIME = 30;

    private static CommandFactory commandFactory;

    private static ObjectMapper objectMapper;

    @Autowired
    public void init(CommandFactory commandFactory, ObjectMapper objectMapper) {
        this.commandFactory = commandFactory;
        this.objectMapper = objectMapper;
    }

    @OnMessage
    public void receive(String message, Session session, @PathParam("did") int documentId,
                        @PathParam("bid") String branchBid) {
        log.info("[websocket] 收到消息：id={}，message={}", session.getId(), message);

    }

    @OnMessage
    public void heartBeat(PongMessage heartBeat, Session session, @PathParam("did") int documentId,
                          @PathParam("bid") String branchBid) {

    }

    // 连接打开
    @OnOpen
    public void onOpen(Session session, @PathParam("did") int documentId, @PathParam("bid") String branchBid) {
        log.info("[websocket] 新的连接：id={}, did={}, bid={}", session.getId(), documentId, branchBid);

    }

    // 连接关闭
    @OnClose
    public void onClose(Session session, CloseReason closeReason, @PathParam("did") int documentId, @PathParam("bid") String branchBid) {
        log.info("[websocket] 连接断开：id={}, did={}, bid={}，reason={}", session.getId(), documentId, branchBid, closeReason);

    }

    // 连接异常
    @OnError
    public void onError(Session session, Throwable throwable,  @PathParam("did") int documentId, @PathParam("bid") String branchBid) throws IOException {
        log.info("[websocket] 连接异常：id={}，throwable={}, did={}, bid={}", session.getId(), documentId, branchBid, throwable.getMessage());

    }
}

@skydream-xu I used your sample code to run, and the result was that the websocket document could be generated. For follow-up discussions, please go to discussions #898
